I have had this Christopher Columbus Souvenir Plate for over 30 years. It was made in 1892 to Commemorate the 400th Anniversary of the discovery of America in Blue Opaque and Milk Glass. It has a beautiful Fleur-De-Lis reticulated border and measures 10" in diameter. I have never been able to find out who made it but as a Past G.K. and an over 43 year member of the K.C., I have always cherished it. RER (LOUMANAL)
